Mulgrew, who also spent seven years playing a starship captain on "Star Trek: Voyager," narrates "The Principle"by ultra-conservative Robert Sungenis, who maintains the blog "Galileo Was Wrong" that claims the Earth is immobile at the center of the universe. He is also a Holocaust denier, according to Raw Story, and probably a really fun guy to sit next to at brunch.

So is Mulgrew a devotee of Sungenis' extremely bogus theory? Unclear. She does say "everything we think we know about our universe is wrong" in the trailer, but apparently not everyone who was in that trailer chose to be there. Scientist Lawrence Krauss assured his Twitter followers that footage of him had been lifted without his knowledge.

For all who asked: Some clips of me apparently were mined for movie on geocentricism. So stupid does disservice to word nonsense. Ignore it.— Lawrence Krauss (@LKrauss1) April 8, 2014

Maybe Mulgrew was misled about the documentary. Honestly, though, I kind of hope she has gone 'round the bend. Lots of celebrities believe insane things, but this, at least, is a new one.
